{ CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They are
under pressure, and if you turn the coolant surge
tank pressure cap — even a little — they can
come out at high speed. Never turn the cap when
the cooling system, including the coolant surge
tank pressure cap, is hot. Wait for the cooling
system and coolant surge tank pressure cap to
cool if you ever have to turn the pressure cap.
If coolant is needed, add the proper DEX-COOL
®
coolant mixture directly to the surge tank, but be sure
the cooling system is cool before this is done.
1. When the cooling system, including the coolant
surge tank pressure cap and upper radiator
hose, is no longer hot, remove the pressure cap.
Turn the pressure cap slowly counterclockwise
about one-quarter turn and then stop.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.
2. Keep turning the pressure cap slowly, and remove it.
